Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of lateral hydraulic vibration dampers. Specifically, it relates to an directional structure for the bottom cover of a lateral hydraulic vibration damper. Background Technology
[0002] In off-road vehicles, high-performance vehicles, and other similar models, lateral hydraulic shock absorbers are key components for suppressing lateral vibrations. Their operational stability directly affects the vehicle's ride comfort and handling safety. Currently, the compression valve seat of most lateral hydraulic shock absorbers adopts a circumferentially uniform structure design.
[0003] In practical use, due to the gravity of the hydraulic fluid, gas tends to accumulate in the upper area between the compression valve seat and the reservoir of the lateral hydraulic shock absorber. When the shock absorber extends, this accumulated gas can easily enter the working cylinder through the compensation hole, causing a short-segment discontinuous damping force during the reciprocating motion of extension and compression. This gap problem prevents the shock absorber from achieving the expected damping effect, making it difficult to meet the high-precision requirements of off-road vehicles and high-performance vehicles for lateral vibration suppression, thus limiting its application experience in these models. Utility Model Content
[0004] Therefore, the technical problem to be solved by this utility model is to provide a bottom cover orientation structure for a transverse hydraulic shock absorber, which can effectively solve the problem that gas in the oil storage cylinder of the transverse hydraulic shock absorber can easily enter the working cylinder, thereby affecting the shock absorption effect.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A directional structure for the bottom cover of a lateral hydraulic shock absorber includes a bottom cover and a compression valve seat. The bottom cover has an outwardly recessed groove, and the compression valve seat corresponding to the groove has a notch. The notch has a protrusion located inside the groove.
[0007] Preferably, the groove is located on the surface where the bottom cover contacts the compression valve seat, and the bottom surface of the groove smoothly transitions from the circumferential surface of the bottom cover to the bottom surface of the groove. The angle α between the opening of the groove on the circumferential surface of the bottom cover and the bottom surface of the groove is 120-130°.
[0008] Preferably, the notch is located on the circumferential surface where the compression valve seat contacts the bottom cover, and the arc length of the central axis of the notch is greater than the arc length of the central axis of the groove opening.
[0009] Preferably, the protrusion and the compression valve seat are an integral structure, located at the center of the notch, and the end face of the protrusion contacts the inner bottom surface of the groove.
[0010] The technical solution of this utility model has achieved the following beneficial technical effects:
[0011] This utility model is scientifically and rationally designed. By designing a groove structure on the mating surface of the oil reservoir bottom cover and the compression valve seat, this groove structure cooperates with the protruding structure of the compression valve seat to ensure that gas does not enter the working cylinder when the damper oil is stretched and compressed, thereby ensuring the continuous effect of the damper, eliminating the backlash phenomenon, making it easy to manufacture, with low modification costs, and providing good social and economic benefits. Attached Figure Description
[0012] Figure 1 This is a schematic diagram of the structure of this utility model;
[0013] Figure 2 This is a front sectional view of the present invention;
[0014] Figure 3 This is a schematic diagram of the bottom cover structure of this utility model.
[0015] The reference numerals in the figure are: 1-bottom cover; 2-compression valve seat; 3-groove; 4-protrusion; 5-notch. Detailed Implementation
[0016] like Figure 1 , 2 As shown, a lateral hydraulic shock absorber bottom cover orientation structure is provided. The bottom cover 1 is provided with an outwardly recessed groove 3. The compression valve seat 2 corresponding to the groove 3 is provided with a notch 5. The notch 5 is provided with a protrusion 4, which is located inside the groove 3.
[0017] like Figure 3 As shown, the groove 3 is located on the surface where the bottom cover 1 contacts the compression valve seat 2. The bottom cover 1 smoothly transitions to the bottom surface of the groove 3 in the circumferential direction. The angle α between the opening of the groove 3 on the circumferential surface of the bottom cover 1 and the bottom surface of the groove 3 is 120-130°.
[0018] like Figure 2 As shown, the notch 5 is located on the circumferential surface where the compression valve seat 2 contacts the bottom cover 1, and the arc length of the central axis of the notch 5 is greater than the arc length of the central axis at the opening of the groove 3.
[0019] The protrusion 4 and the compression valve seat 2 are an integral structure, located in the center of the notch 5, and the end face of the protrusion 4 is in contact with the inner bottom surface of the groove 3.
[0020] The transverse hydraulic shock absorber is assembled transversely (horizontally) during use. In this utility model, the bottom cover and compression valve seat of the existing transverse hydraulic shock absorber can be replaced. After the shock absorber is assembled, the bottom cover 1 with the protrusion is installed at the lower end, that is, the groove 3 is located at the bottom. The structure of this groove 3 cooperates with the protrusion 4 of the compression valve seat. The protrusion 4 and the groove 3 are in the same direction. No compensation holes are left in other positions, so that when the shock absorber oil is stretched and compressed, gas will not enter the working cylinder, thus ensuring the continuous effect of the shock absorber and no backlash.
[0021] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
